Hi,

I was wondering if you guys knew of an indicator similar to “SWING” from ninja trader.

…"NinjaTrader, plots horizontal lines that represent the swing high and low points for a charted instrument. This intuitive lagging indicator offers a quick and easy method to determine when price moves out of a range based on a user defined “lookback period”.
